Description

Technical Field

[0001] The present application belongs to the field of electrical appliance technology, and specifically relates to a method, device and equipment for dehydrating clothes. Background Art

[0002] The dehydration process of the clothing treatment equipment requires the drum to rotate at high speed, using centrifugal force to spin out the water adhering to the clothes to be treated. However, due to uneven distribution of clothes and other reasons, high-speed rotation may cause a large eccentricity in the inner drum of the clothing treatment equipment, resulting in unbalanced dehydration, noise, displacement, or the clothes to be treated cannot be spun dry for a long time.

[0003] In the existing method, when dehydrating the clothes to be processed, the eccentricity threshold is usually set according to manual experience; if the eccentricity value of the inner drum during the dehydration process is not within the range of the eccentricity threshold, the speed of the inner drum cannot be increased; only when the eccentricity value of the inner drum during the dehydration process is within the range of the eccentricity threshold, the speed of the inner drum can be increased to achieve dehydration of the clothes.

[0004] However, although this method avoids some eccentric vibration problems, the inner drum speed will only be increased when the eccentricity value of the inner drum is within the range of the manually set eccentricity threshold value, which will prolong the dehydration time of the clothing processing equipment. In addition, it is difficult to accurately and quickly control the increase in the drum speed using a fixed threshold method. For clothes with a large amount of water absorption, the speed may not be increased for a long time, resulting in poor dehydration effect of the clothes. Summary of the invention

[0076] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0077] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0078] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein, for example.

[0079] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0080] The dehydration process of the clothing treatment equipment requires the drum to rotate at high speed, using centrifugal force to spin out the water adhering to the clothes to be treated. However, due to uneven distribution of clothes and other reasons, high-speed rotation may cause a large eccentricity in the inner drum of the clothing treatment equipment, resulting in unbalanced dehydration, noise, displacement, or the clothes to be treated cannot be spun dry for a long time.

[0081] In the existing method, when dehydrating the clothes to be treated, an eccentricity threshold is usually set according to manual experience; if the eccentricity value of the inner drum during the dehydration process is not within the range of the eccentricity threshold, the speed of the inner drum cannot be increased. At this time, the distribution of the clothes will be redistributed along with the speed of the inner drum, and the eccentricity value of the clothes processing device is repeatedly obtained until the eccentricity value is lower than the threshold, and the drum speed is increased to dehydrate the clothes to be treated; when the eccentricity value of the inner drum during the dehydration process is within the range of the eccentricity threshold, the speed of the inner drum is directly increased to achieve dehydration of the clothes.

[0082] However, although this method avoids some eccentric vibration problems, the inner drum speed will only be increased when the eccentricity value of the inner drum is within the range of the manually set eccentricity threshold value, which will prolong the dehydration time of the clothing processing equipment. In addition, it is difficult to accurately and quickly control the increase in the drum speed using a fixed threshold method. For clothes with a large amount of water absorption, the speed may not be increased for a long time, resulting in poor dehydration effect of the clothes.

[0083] In view of the above problems, the present application provides a method for dehydrating clothes. Figure 1 Schematic diagram of the scene of clothes dehydration provided by this application. Figure 1 As shown, the clothing processing device 1 is in communication connection with the cloud server 2. The clothing processing device 1 can perform simple calculations and analysis on the data in the clothing processing process, and the cloud server 2 can perform complex calculations on the data in the clothing processing process to obtain a more accurate data processing result.

[0084] The present application provides a method for dehydrating clothes, which utilizes the cloud computing power of the Internet of Things and adopts end-cloud collaboration to construct a method for calculating, updating and modeling control of eccentric time series features of clothing processing equipment; first, offline training of time series deep feature extraction and decision models of different feature combinations is performed on the cloud, and classification is performed according to the complexity of feature calculation, and simple features and decision models are written into the terminal electronic control program; secondly, complex time series feature calculations are completed on the cloud, and these features are updated to the terminal at a lower sampling rate; finally, on the terminal side, when complex features are not updated, a simple feature decision model is used for control, and when complex features are received, a complex feature decision model is used for control; the method adopts an end-cloud collaborative approach to ensure seamless switching of real-time control of clothing processing equipment, avoid the problem of vibration of clothing processing equipment during the dehydration stage in advance, ensure clothing dehydration efficiency, and improve user experience.

[0085] Figure 2 is a flow chart of the clothing dehydration method provided by the present application. The execution subject of this embodiment can be, for example, Figure 1 The laundry processing device shown in the embodiment. Figure 2 As shown, the clothes dehydration method provided in this embodiment includes:

[0086] S101: Acquire parameter information of a clothes treating device in a first dehydration stage, and determine a simple characteristic value of the first dehydration stage according to the parameter information.

[0087] The clothing processing device may be, for example, a washing machine, a care machine, or a drying machine. The first dehydration stage is used to indicate the dehydration stage at the beginning of the dehydration program. It is understandable that the first dehydration stage is mainly used to analyze the degree of eccentricity of the inner drum in the dehydration program, that is, the dehydration speed in the first dehydration stage is relatively low.

[0088] The parameter information is used to indicate the eccentricity value and the drum speed of the clothing processing device in the dehydration stage. The parameter information of the first dehydration stage may be: the eccentricity time series data of the eccentricity value changing with time, the drum speed time series data of the drum speed changing with time, and the corresponding relationship between the eccentricity value and the drum speed. The simple characteristic value is used to indicate the characteristic value of the eccentricity value and the characteristic value of the drum speed in the first dehydration stage. The simple characteristic value may be, for example, the average value, the maximum value, the minimum value, the variance, the inflection point, and the number of inflection points.

[0089] It can be understood that in this step, by obtaining the eccentricity time series of the eccentricity value of the clothes processing device in the first dehydration stage and the drum speed time series of the drum speed changing with time, the corresponding relationship between the eccentricity value and the drum speed of the clothes processing device can also be obtained. The eccentricity time series and the drum speed time series are feature extracted to obtain the simple eigenvalue of eccentricity and the simple eigenvalue of drum speed.

[0090] This step can use tsfresh's built-in feature algorithm to calculate simple feature values. Among them, tsfresh is mainly used to perform system feature engineering from time series and other sequence data. The common point between time series data and other sequence data is that they are sorted by independent variables. The most common independent variable is time (that is, the most common data processed by tsfresh is time series data). tsfresh can automatically calculate a large number of time series features.

[0091] For example, the dehydration time of the clothing processing equipment is 7 minutes, and the first dehydration stage may be the first minute after the dehydration stage begins. Therefore, the eccentricity time series of the eccentricity value changing with time within the first minute of the dehydration stage and the drum speed time series of the drum speed changing with time may be obtained, and the built-in feature algorithm of tsfresh is used to calculate the eccentricity simple eigenvalue and the drum speed simple eigenvalue for the eccentricity time series and the drum speed time series respectively.

[0092] S102: According to the simple feature value, a simple feature decision model is used to predict the operating state of the clothing processing device in the second dehydration stage, and the simple feature decision model is trained according to the eccentricity value of the inner drum of the clothing processing device in historical data.

[0093] Among them, the simple feature decision model is one of the decision models constructed in the cloud by performing feature extraction, feature correlation evaluation and feature complexity analysis on the historical eccentric sample set.

[0094] The operating status is used to indicate whether the clothing processing equipment will vibrate in the second dehydration stage. When the clothing processing equipment vibrates, it indicates that the distribution of the clothes in the drum of the clothing processing equipment is unreasonable, and the clothes in the drum need to be redistributed; when the clothing processing equipment does not vibrate, it indicates that the distribution of the clothes in the drum of the clothing processing equipment is reasonable. At this time, the clothes in the drum do not need to be redistributed, and the clothes to be processed can be efficiently dehydrated.

[0095] The dehydration program includes: a first dehydration stage and a second dehydration stage. The dehydration speed of the second dehydration stage is greater than the dehydration speed of the first dehydration stage. After entering the dehydration program, the clothing processing device will first perform dehydration processing at a smaller dehydration speed in the first dehydration stage. When the first dehydration stage is over, the clothing processing device will perform dehydration processing at a normal or larger dehydration speed in the second dehydration stage. That is: first determine whether the clothing processing device has vibration in the second dehydration stage based on the parameter information of the first dehydration stage. If so, it is necessary to adjust the speed of the second dehydration stage based on the parameter information of the first dehydration stage. If not, the dehydration processing can be performed using the dehydration speed corresponding to the second dehydration stage.

[0096] It can be understood that the clothing processing equipment adopts a simple feature decision model to predict the eccentricity time series of the eccentricity value of the clothing processing equipment changing with time and the drum speed time series of the drum speed changing with time in the second dehydration stage based on the simple characteristic value of eccentricity and the simple characteristic value of drum speed in the first dehydration stage, and determines the operating state of the second dehydration stage based on the correlation between the eccentricity value, the drum speed and the vibration of the clothing processing equipment.

[0097] For example, if the dehydration time of the clothes processing equipment is 7 minutes, the second dehydration stage may be 6 minutes after the dehydration stage, therefore, the eccentricity time series of the eccentricity value changing with time and the drum speed time series of the drum speed changing with time may be obtained 6 minutes after the dehydration stage. The correlation between the eccentricity value, the drum speed and the vibration of the clothes processing equipment is a data result obtained by manual observation and analysis.

[0098] S103: adjusting the parameter information according to the operating state to obtain new parameter information, and controlling the clothing processing device to perform dehydration processing according to the new parameter information in the second dehydration stage.

[0099] Among them, the new parameter information is used to indicate the eccentricity value and drum speed re-determined by the clothing processing device. The eccentricity value and drum speed can be fixed values, or can vary with the increase in dehydration time, that is, the eccentricity time series and drum speed time series of the second dehydration stage are set. The eccentricity value and drum speed are not set to fixed values ​​to ensure that the clothing processing device can ensure and improve the dehydration effect of the clothes under the condition that the clothing processing device does not vibrate when the clothing processing device dehydrates the clothes to be treated. However, the eccentricity value and the drum speed are values ​​within a range. If the eccentricity value and the drum speed are set too low, it will lead to problems such as too long dehydration time of the clothes or the clothes to be treated cannot be spun dry. If the eccentricity value and the drum speed are set too high, it will easily cause the clothes to be treated to be torn or the clothes to have too many wrinkles after dehydration.

[0100] It can be understood that the operating state includes vibration operation and normal operation. If the clothing processing device generates vibration, it indicates that the distribution of the clothing in the drum of the clothing processing device is unreasonable. At this time, the clothing in the drum needs to be redistributed, that is, the clothing to be processed in the drum of the clothing processing device can be dispersed by adjusting the rotation speed in the drum, and the clothing to be processed can be redistributed in the drum under the rotation of the inner drum. Therefore, the rotation of the inner drum can be controlled according to the new drum speed time sequence, so that the clothing to be processed can be dehydrated; if the clothing processing device does not generate vibration, it indicates that the distribution of the clothing in the drum of the clothing processing device is reasonable. In order to improve the dehydration efficiency of the clothing, a suitable drum speed can be set, and the rotation of the inner drum can be controlled according to the new drum speed time sequence, so that the clothing to be processed can be dehydrated.

[0101] For example: the dehydration time of the clothing processing equipment is 7 minutes, and the second dehydration stage can be 6 minutes after the dehydration stage. The eccentricity time series of the eccentricity value changing with time 6 minutes after the dehydration stage and the drum speed time series of the drum speed changing with time are the current parameter information. The current parameters can be readjusted according to the correlation between the eccentricity value, the drum speed and the vibration of the clothing processing equipment under the operating conditions, and the clothing processing equipment can be controlled to perform dehydration according to the adjusted parameter information.

[0102] The present embodiment provides a method for dehydrating clothes, which obtains parameter information of a clothes processing device in a first dehydration stage, and determines a simple characteristic value of the first dehydration stage based on the parameter information, and predicts an operating state of the clothes processing device in a second dehydration stage based on the simple characteristic value using a simple feature decision model, and adjusts the parameter information according to the operating state to obtain new parameter information, and controls the clothes processing device to perform dehydration according to the new parameter information in the second dehydration stage; the method avoids the problem of vibration of the clothes processing device in the dehydration stage, ensures the dehydration efficiency of the clothes, and improves the user experience.

[0103] Figure 3 : is a flow chart of the clothing dehydration method provided by this application. Figure 3 As shown, in this embodiment Figure 2 Based on the embodiment, the clothes dehydration treatment method is described in detail. The clothes dehydration treatment method shown in this embodiment includes:

[0104] S201: The clothes processing device obtains parameter information of a first dehydration stage, and determines a simple characteristic value of the first dehydration stage according to the parameter information.

[0105] Among them, step S201 is similar to the above-mentioned step S101 and is briefly described here. The executor in this step is the clothing processing device. The clothing processing device obtains the parameter information of the first dehydration stage and can analyze and process the data to obtain the operation result of the clothing processing device, or transmit the data to the cloud server.

[0106] S202: The clothing processing device sends the parameter information to a cloud server.

[0107] Among them, parameter information refers to the parameter data of the clothing processing device itself during its operation. Therefore, the parameter information can be calculated and processed by the processor in the clothing processing device, and can also be calculated and processed by the cloud server. Since the processor in the clothing processing device processes the parameters in a relatively simple way, the accuracy of the processed results is relatively low (this is determined by the computing power of the processor); and the cloud server can perform more complex calculations on the parameter information, and the accuracy of the processed results is relatively high. Therefore, the clothing processing device can send the parameter information to the cloud server so that the cloud server can perform complex calculations based on the parameter information.

[0108] S203: The cloud server determines the complex characteristic value of the first dehydration stage according to the parameter information.

[0109] Among them, the complex eigenvalue is used to indicate the eigenvalue of the eccentricity value and the eigenvalue of the drum speed in the first dehydration stage. Since the executor of this step is the cloud server, and the cloud server has strong computing power, the complex eigenvalue can be obtained by calculating the parameter information of the first dehydration stage.

[0110] It can be understood that in this step, by obtaining the eccentricity time series of the eccentricity value of the clothes processing device in the first dehydration stage and the drum speed time series of the drum speed changing with time, the corresponding relationship between the eccentricity value and the drum speed of the clothes processing device can also be obtained. The eccentricity time series and the drum speed time series are feature extracted to obtain the simple and complex eigenvalues ​​of the eccentricity and the complex eigenvalues ​​of the drum speed.

[0111] In this step, the complex eigenvalues ​​can be calculated using the neural network model, that is, the parameter information is input into the neural network model so that the neural network model outputs the corresponding complex eigenvalues.

[0112] For example, the first dehydration stage is the first minute of dehydration of the clothes to be treated. The eccentricity value and drum speed of the first minute of dehydration of the clothes to be treated can be input into the neural network model, and the neural network model will analyze the data to obtain the complex characteristic values ​​of the data.

[0113] S204: The cloud server sends the complex characteristic value of the first dehydration stage to the clothing processing device.

[0114] The cloud server sends the complex feature value to the clothing processing device so that the clothing processing device can dynamically update the original complex feature value according to the complex feature value sent by the cloud server. At the same time, sending the complex feature value can also enable the clothing processing device to determine the current connection status with the cloud server.

[0115] S205: The clothing processing device determines whether the complex feature value fed back by the cloud server is received within a preset time period; if so, execute step S206.

[0116] The clothing processing device and the cloud server may be in a connected state or in an offline state. When the clothing processing device is in a connected state, the clothing processing device can receive the complex feature value fed back by the cloud server; when the clothing processing device is in an offline state, the clothing processing device cannot receive the complex feature value fed back by the cloud server.

[0117] This step determines whether the clothing treatment device can receive the complex characteristic value fed back by the cloud server, so as to determine which model to use to predict the operation status of the second dehydration stage. The purpose of setting the preset time in this step is to avoid network delay caused by network instability.

[0118] It is understandable that, since the cloud server can perform complex calculations, the operating status predicted by the cloud server is more accurate; since the clothing processing device itself can only perform simple calculations, the operating status predicted by the processor of the clothing processing device is less accurate. It is precisely because of the different levels of complexity of the above two operations that this step needs to determine whether the complex feature value fed back by the cloud server can be received to determine whether to use the operating status predicted by the simple feature decision model or the operating status predicted by the complex feature decision model for parameter adjustment.

[0119] When the clothing processing device receives the complex feature value fed back by the cloud server within the preset time, it indicates that the clothing processing device is currently in a connected state, so subsequent predictions can be made through the complex feature decision model set on the cloud server; when the clothing processing device cannot receive the complex feature value fed back by the cloud server within the preset time, it indicates that the clothing processing device is currently in an offline state, so subsequent predictions can only be made through the simple feature decision model set on the clothing processing device.

[0120] S206: The clothes processing device predicts the operating state of the second dehydration stage according to the simple feature value using a simple feature decision model.

[0121] The simple feature decision model inputs the simple feature value of eccentricity and the simple feature value of drum speed in the first dehydration stage into the model, analyzes and processes the simple features, and thus predicts the operating state of the clothing treatment device in the second dehydration stage. The operating state here is used to characterize whether the clothing treatment device vibrates in the second dehydration stage. The operating state includes: vibrating operation and normal operation.

[0122] It is understandable that this step will be executed regardless of whether the clothing processing device receives the complex characteristic value fed back by the cloud server. That is, after the simple characteristic value is determined according to the parameter information, this step can be executed regardless of whether the complex characteristic value fed back by the cloud server is received. This is because the clothing processing device cannot confirm whether it will receive the complex characteristic value fed back by the cloud server in the future. Therefore, in order to avoid not receiving the complex characteristic value and ensure the normal operation of the dehydration program, this step will be executed.

[0123] Optionally, the specific implementation method of this step may be: inputting the simple feature value into a simple feature decision model to obtain the first predicted state information output by the simple feature decision model; and determining the operating state of the clothing processing equipment in the second dehydration stage based on the first predicted state information.

[0124] The first predicted state information is used to indicate the eccentricity time series and the drum speed time series of the clothes processing device in the second dehydration stage. Simple features Since the feature values ​​are relatively simple, the clothes processing device can use a simple feature decision model to analyze and process the simple features, predict the eccentricity time series and the drum speed time series of the clothes processing device in the second dehydration stage, and determine the operating state of the second dehydration stage according to the correlation between the eccentricity value, the drum speed and the vibration of the clothes processing device.

[0125] S207: The cloud server inputs the complex feature value into a complex feature decision model to obtain second prediction state information output by the complex feature decision model.

[0126] The second prediction state information is used to indicate the eccentricity time series and drum speed time series of the clothes processing device in the second dehydration stage. Since the eigenvalues ​​of complex features are relatively complex, the computing power of the cloud server is relatively strong, and the results are relatively accurate, therefore, a complex feature decision model can be used on the cloud server to analyze and process the complex features and predict the eccentricity time series and drum speed time series of the clothes processing device in the second dehydration stage.

[0127] S208: The cloud server determines the operating status of the second dehydration stage according to the second predicted status information.

[0128] The operating state refers to the vibration condition of the clothes processing device, which can be: vibration operation and normal operation. Vibration operation can cause significant damage to the clothes processing device. Therefore, in this embodiment, it is necessary to avoid the clothes processing device being in vibration operation. Normal operation can ensure that the clothes processing device operates at a reasonable drum speed, which can reduce damage to the clothes processing device.

[0129] It can be understood that the cloud server predicts the eccentricity time series and the drum speed time series of the second dehydration stage by analyzing the eccentricity time series and the drum speed time series of the first dehydration stage, and determines the operating status of the second dehydration stage based on the correlation between the eccentricity value, the drum speed and the vibration of the clothing processing equipment.

[0130] S209: The cloud server sends the operating status of the second dehydration stage to the clothing processing device.

[0131] Among them, since the program of the clothing processing equipment is directly controlled by the control device in the clothing processing equipment, the cloud server needs to send the operating status of the clothing processing equipment in the second dehydration stage to the clothing processing equipment, so that the control device of the clothing processing equipment can control the clothing processing equipment according to the operating status of the clothing processing equipment, thereby avoiding vibration of the clothing processing equipment during the dehydration stage.

[0132] S210: The clothing processing device adjusts the parameter information according to the operating state to obtain new parameter information.

[0133] Among them, vibration operation indicates that the clothes processing device will vibrate in the second dehydration stage due to unreasonable distribution of the clothes to be processed, and the clothes to be processed need to be redistributed, so the parameter information needs to be adjusted. Normal operation indicates that the clothes processing device will not vibrate in the second dehydration stage, and the clothes to be processed can be dehydrated according to the estimated parameters of the second stage.

[0134] It is understandable that the operating state can be predicted by the clothing processing device through a simple feature decision model, or can be predicted by the cloud server through a complex feature decision model. When the clothing processing device is in an offline state, the operating state predicted by the simple feature decision model is used; when the clothing processing device is in a connected state, the operating state predicted by the complex feature decision model is used.

[0135] Optionally, if the operating state is vibration operation, the inner drum rotation speed is reduced to a first preset rotation speed; if the operating state is normal operation, the inner drum rotation speed is increased to a second preset rotation speed, wherein the first preset rotation speed is less than the second preset rotation speed.

[0136] It is understandable that the clothes treatment equipment is in vibration operation, and at this time, the state of the clothes to be treated in the drum needs to be redistributed, and the clothes to be treated need to be spread out by the rotation of the drum to achieve the effect of redistribution. When the drum speed is high, the clothes to be treated are close to the inner drum wall, and the inner drum speed needs to be reduced to change the distribution of the clothes to be treated, so as to dehydrate the clothes to be treated. The normal operation of the clothes treatment equipment indicates that the clothes are reasonably distributed, and the drum speed can be increased according to the current trend of the drum speed change to ensure that the clothes treatment equipment does not vibrate while efficiently dehydrating the clothes to be treated.

[0137] S211: The clothes processing device controls the second dehydration stage to perform dehydration processing according to the new parameter information.

[0138] Among them, the control module of the clothing processing equipment adjusts the parameters of the clothing processing equipment according to the new parameter information, so as to dehydrate the clothing to be processed, so that the clothing to be processed can achieve the dehydration effect while preventing the clothing processing equipment from vibrating during the dehydration stage.

[0139] Exemplarily, the simple decision model and the complex decision model are trained by the cloud server based on the historical eccentric sample set, and the specific training process is as follows:

[0140] A historical eccentricity sample set sent by the clothing processing device is obtained, wherein the historical eccentricity sample set is used to indicate the eccentricity of the inner drum of the clothing processing device during a historical dehydration stage; feature extraction is performed on the historical eccentricity sample set to obtain a target feature, wherein the target feature is a feature that has a correlation with the eccentricity value of the inner drum; the target features are classified according to computational complexity to obtain a simple target feature set and a complex target feature set; the simple target feature set is used to train a first feature decision model to obtain all simple feature decision models; the complex target feature set is used to train a second feature decision model to obtain all complex feature decision models.

[0141] Among them, the historical eccentricity sample set is the data information collected during the operation of historical clothing processing equipment. The data information can be used for model training in the cloud. tsfresh is used to extract the features of the eccentricity sample time series data, and LSTM is used to extract implicit features with historical correlation information. The DeepCheck evaluation algorithm is used to evaluate the correlation of the extracted features, and retain features with high correlation with eccentricity control. The features are classified according to the complexity of the calculation of each feature, and are divided into simple feature sets and complex feature sets. Then, two decision models (i.e., simple decision models and complex decision models) are trained based on the simple feature set and the complex feature set (or the full feature set) respectively.

[0142] LSTM (Long Short-Term Memory Network) is a time recurrent neural network specially designed to solve the long-term dependency problem of general RNN (recurrent neural network). All RNNs have a chain form of repeated neural network modules. In standard RNN, this repeated structural module has only a very simple structure, which can extract the more important and difficult to find features of the data. DeepCheck's evaluation algorithm divides the eccentric sample set into a training set, a validation set, and a test set to obtain a simple decision model with low computational complexity and a complex decision model with high computational complexity. The simple decision model is written into the data processor of the clothing processing equipment to perform simple calculations on the parameters generated during the operation of the clothing processing equipment under its own computing power conditions, while the complex decision model will be written into the cloud server, using the strong algorithm capabilities of the cloud server to perform complex calculations on the parameter information to obtain more accurate results.

[0143] The present embodiment provides a method for dehydrating clothes, which obtains parameter information of a clothes processing device in a first dehydration stage, determines a simple characteristic value of the first dehydration stage according to the parameter information, and sends the parameter information to a cloud server, so that the cloud server determines a complex characteristic value of the first dehydration stage according to the parameter information, and determines whether the complex characteristic value fed back by the cloud server is received within a preset time. If the complex characteristic value fed back by the cloud server is received within the preset time, the operating state of the clothes processing device in the second dehydration stage sent by the cloud server is obtained, and if the complex characteristic value fed back by the cloud server is not received within the preset time, the operating state of the clothes processing device in the second dehydration stage sent by the cloud server is obtained. The complex feature value fed back by the server is used, and a simple feature decision model is used according to the simple feature value to predict the operating state of the clothing processing device in the second dehydration stage; if the operating state is vibration operation, the inner drum speed is reduced to a first preset speed; if the operating state is normal operation, the inner drum speed is increased to a second preset speed, and the clothing processing device is controlled to perform dehydration according to the new parameter information in the second dehydration stage; the method adopts an end-cloud collaborative approach to ensure seamless switching of real-time control of the clothing processing device, avoid the problem of vibration of the clothing processing device in the dehydration stage in advance, ensure the dehydration efficiency of the clothing, and improve the user experience.
